  • Patent number: 11338130
    Abstract: Some embodiments of an electrical stimulation system employ wireless electrode assemblies to provide pacing therapy, defibrillation therapy, or other stimulation therapy. In certain embodiments, the wireless electrode assemblies may include a guide wire channel so that each electrode assembly can be advanced over a guide wire instrument through the endocardium. For example, a distal tip portion of a guide wire instrument can penetrate through the endocardium and into the myocardial wall of a heart chamber, and the electrode assembly may then be advanced over the guide wire and into the heart chamber wall. In such circumstances, the guide wire instrument (and other portions of the delivery system) can be retracted from the heart chamber wall, thereby leaving the electrode assembly embedded in the heart tissue.

  • Patent number: 11144424
    Abstract: A system writes to a replicated direct access storage device (DASD) a record of each step within a job as each step begins and as each step completes. The records are maintained on the replicated DASD for a predetermined period of time. The predetermined period of time is, for example, the greatest amount of lag in replication of all storage systems operating within the system. The records are stored, for example, in an open jobs and datasets (OJD) file, where the file itself is a dataset. The dataset is written to by an online task (e.g., OJDSTC) which gathers input from two sources. Upon job completion, the records are stored, for example, in an OJD journal and removed from the OJD file.

A patient is monitored during an observation time period while the patient performs prescribed physical stressors and by applying pacing stimulus stressors to a medical device. Physiological measures are stored from the observation period, including at least one of direct measures regularly recorded on a substantially continuous basis by the medical device and measures derived therefrom. The measures that originate from the observation time period as a reference baseline for the patient are identified. The reference baseline and those measures originating subsequent to the observation period are evaluated. The measures are analyzed to detect any trends, including one of a status quo and a change in cardiac performance of the patient. Each trend is compared to parameters corresponding to worsening heart failure indications to generate a notification of parameter violations.

The method includes determining a tissue overgrowth correction factor that accounts for the optical properties of the tissue that cause scattering of the emitted light to a light detector and the relative amplitudes of the emitted light wavelengths. A corrected time interval measured for infrared light is based on an infrared signal returned from fluid with no tissue overgrowth. A corrected time interval for red light is determined by subtracting a red light signal attributed to the presence of tissue overgrowth. The amount of red light signal attributed to the presence of tissue overgrowth is proportional to the total infrared signal less the nominal infrared signal.

  • Publication number: 20020125991
    Abstract: A method and apparatus for simultaneously determining a patient's identification and blood oxygen saturation are provided. An pulse oximeter probe carries a light source such as LEDs or lasers which is used to read patient identification information carried on the patient's wristband by a bar code. Alternately, the patient's wristband incorporates a radio frequency reader chip which contains the patient's identification information and the pulse oximeter probe carries an antenna adjacent its cable so that, when the pulse oximeter is turned on, it reads the chip in the wristband during the same motion with which the patient's oxygen blood saturation is measured with the pulse oximeter.

  • Patent number: 6415166
    Abstract: A photoplethysmographic monitoring system such as a pulse oximeter collects data regarding the blood analyte concentration and pulse rate of a patient through the analysis of light transmitted form an emitter through tissue to a photo detector. It is often necessary to review the collected data, such as oxygen saturation, pulse rate and pulsatility value at a location remote to the patient being monitored. The photoplethysmographic system formats the selected data for transmittal to a remote facsimile machine via standard telephone communication systems using an internal or external modem. The formatter is able to function within the processing and memory constraints of pulse oximeters by formatting and transmitting the data in sections. Formatted data may be sent via hard-wired telephone, cellular phone, PCS digital telephones or through satellite communication systems enabling transmittal of data from a portable photoplethysmographic system.

  • Patent number: 6226540
    Abstract: The invention relates to a measuring process, the purpose of which is to increase the measuring accuracy of pulse oxymeters and comparable optical devices which are used in vivo to ascertain oxygen saturation of arterial blood. The measuring process according to the invention is provided for the purpose of ascertaining oxygenation of arterial blood in tissue by evaluating the differential light attenuation at several wavelengths. It is characterized by the fact that light attentuation of at least one wavelength is determined in order to choose those calibration curves of several variables (&OHgr;1, &OHgr;2, . . . ) produced by different wavelength pairings with a minimized error in order to generate an output signal for the arterial blood oxygenation.

  • Patent number: 5995857
    Abstract: Apparatus and method for biofeedback of human central nervous system activity using radiation detection. This invention uses radiation from the brain resulting either from an ingested or injected radioactive material or radio frequency excitation or light from an external source impinging on the brain. The radiation is measured by suitable means and is made available to the subject on which the measurement is being made for his voluntary control. The measurement may be metabolic products of brain activity or some quality of the blood, such as its oxygen content. One such system utilizes red and infrared light to illuminate the brain through the translucent skull and scalp. Absorption and scattering of incident radiation depends on the degree of oxygen saturation of the blood in the illuminated tissue.
